What is the standard test pressure for a landing valve body?

The body must be hydrostatically tested to 2.1 MPa (approx. 21.4 kgf/cm²) for 2.5 minutes without any leakage (Clause 7.1).

What material is the landing valve body made from?

The body is typically made from Leaded Tin Bronze (Gunmetal) conforming to Grade LTB 2 of IS 318 (Table 1).

What is the required flow rate for a landing valve?

It must deliver a flow of not less than 900 litres per minute when a flowing pressure of 0.7 MPa is applied at the inlet (Clause 7.3).

What are the standard sizes for landing valves?

The standard nominal size is 63 mm, with flanged or screwed inlets and a 63 mm female instantaneous outlet as per IS 903.

Practical Notes

Always ensure the product has the BIS Standard Mark (ISI mark) to certify its compliance.

Verify that the outlet connection (female instantaneous) is compatible with the local fire brigade's hose couplings (as per IS 903).

During installation, ensure the valve is positioned at the specified height (typically 0.75m to 1.0m from floor level) with sufficient clearance for operation.
